Re: force trim seized?
If worse comes to worse, remove the valve on the front of the pump--yeah, oil will drain out but you will be able to lift the engine by hand.
And I have in my garage a block that was described to me as a 115 Force when I bought it. I never checked the number with Merc data base so I don't know for sure, but it is 2,80 stroke by 3.375 bore just like most of the old Chrysler 115. But, a Force 115 is not listed anywhere I know of. Doesn't mean they didn't make a few though. Only changes it would have needed would have been port timing--if that. May have just re-badged a 120--after all 5 hp is only 4% of a 120. Easy for the factory to make a couple of hundred to couple of thousand if they wanted to gauge the market to compete with OMC, Merc, and Yammy 115. Course, later on it was Merc. so if they made them at all it would be to say they had a complete line. Factory and marketing does things for reasons we don't know. For example: I just found out that in the early '80s Chrysler made a 4 cylinder 90 hp. At this time it was mandated by the manufacturers association that all outboards would have hp measured at the prop so factory just re-badged a 105 into a 90.
At the top rear of the block on the port side of the #1 cylinder, there usually (not always) is a stamped number. Call Merc and give them this number and they can tell you everything you ever wanted to know about your engine.
